To all whom t may concern.'

Be it known that I, GUSTAF ALBIN Nn.- soN, a citizen of the UnitedStates, and resi dent of Chicago, county of Cook, and State of Illinois,have invented certain new and useful Improvements in Plumbing Systems,of which the following is a specification, and which are illustrated inthe accom* panying drawings, forming a part thereof. The inventionvrelates to plumbing, and contemplates certain improvements upon theplumbing system as shown in Patent N o. 993,095, issued to me on May 23,1911.

The object of the invention is to facilitate the installation ofplumbing in buildings, and to this end the invention proposes the use ofcertain improved iittings which are adapted for adjustable connectionwith the plumbing fixtures.

A feature of the invention permits of a confinement of the connectionswhich are extended through the floors within a reduced depth whereby theinstallation of the plumbing in buildings which have fioors of reducedthickness, such as concrete buildings, is accomplished without theextension of any part of the plumbing under the ceiling of a lo weriioor.

In the accompanying drawings, Figure 1 is a side elevation, partly insection showling an arrangement of the vplumbing for connection with thebath. room fixtures in a building comprising a plurality of floors,Figs. 2 and?) are detail perspective views showing certain of the'iittings employed in the plumbingj system illustrated in Fig. 1, p is acentral transverse sectional view ofanotherfitting, Fig. 5 is a detailplan view of the plumbing system partly in section` Fig. 6 is asectional view showing the manner in which the wash basin may beconnected with the plumbing system, Figs. 7 and S are detail perspectiveviewsfshowing the ldrain connections for the bath tub, Fig. 9 is asectional view taken on the line 9-9 of Fig. 5, and Fig. 10 is similarto Fig. 5, but shows a form of construction which may be used when twobath rooms are located upon opposite sides of a common intermediatewall.

thel iioors of the building. Similarly, a. main vent pipe 17 is providedand this main vent pipe extends, as usual, from the lowest floor uponwhich fixtures are provided eo to a connection, -as 18, with the stack15, which is above the so-called water level.

In the simple form of construction illustrated in Fig. 1, each 'of thebranches 16 of the main waste pipe 17, inclined nipple 19, and anupwardly facing hub or 'nipple 20. 'llhe nipple 19 serves for receivingthe end of a drain pipe 21, which drain pipe is in turn connected withboth the lavatory, indicated at 22, bath tub, as 23. As shown, the drainpipe 21 extends in nearly a horizontal direction at substantially thefloor level and is formedA with two receivinghubs 2d and 24, The

bath tub drain pipe 26 is preferably -con- '35 nected with the hub 2iand continues in the saine direction with the drain pipe 21. Thelavatory drain pipe 25, on the other hand, is vertical, and is connectedwithr the `hub 24a. The closet drain. as 27, with the upwardly facinghub or nipple 20 of the waste pipe branch 1G.

Separate vent connections 28, 29 and 30 are provided for the closet 31,the lavatory 22 and the bath tub 23 respectively. The 85 lavatoryconnection is illustrated in detail in Figs. 4 and 6. It preferablyincludes a fitting 32, having alined'nipples 33 and 36 at its top andbottom and an offset downwardly facing discharge arm 34. The dis 90charge arm 34 of the fitting 32 is connected with the drain pipe 25. Thenipple 33 at the top of the itting 32, on the other hand, receives thelower end of the vent connection` 29. An elbow 35 is connected with the.95

remaining nipple, as 36, of the fitting 32, and the drain, as 37, fromthe lavatory bowl 22, is connected with the elbow 35. lThe use of theelbow 35, and its connection with the lower end of the fitting 32,permits of a 100A -wide range of angular adjustment in the lavatorydrain 37. The length of the lava-A tory drain 37 is further renderedadjust`v ably by mounting a bushing 38 in the endl,

of the elbow 35 for telesc'opically receiving 125 the inner end of thedrain 37, in a. well known nia-nner.

The bath tub drain pipe 26 and vent connection 30 are preferably enteredin two of the sockets 39, 40, of a 3-arm tting 411. The .11

third socket, as 42, of the tting serves for receiving one end of anelbow 43. The other is formed with an Fig. 5, and the is connected 8oend of the elbow 43 is connected with a clean-,out drum 46, at one side,as through a nipple 44, which is formed on the side of thel drumadjacent its lower end. Inevent the bath tub 23 is located at somedistance from the wall (not shown), a length of pipe 45, will lbeextended between the elbow 43 and ably formed upon the side the druin 46adjacent its'lower end, serves for receiving the nipple 44. A secondnipple 47, preferthe drain connection, as 48, from the bath n `tub 23. r

The use of the elbow 43 and its connection wth'the socket 42, permits ofthe drum 46 being located at any convenient place upon thefbath roomfloor, as 49. 1 Furthermore, the location of both of the nipples 44 and47 upon the side of the drum 46 permits of the fittings being confinedwithin a depth which' is not greater than the thickness of the licor,even though the floor may bei of reduced thickness, as when made ofconcrete. Itwill be understood that the drum 46 has the usual evenuponremoval of the cover 50. 'Ehe loremovable cover 50, and that thiscover is exposed upon the bath room floor, where it isreadily-accessible. It will ybe noted, however," that'the elbow 43 andthe receiving bend, as 51 of the drain 48, form a trap,

whereb thechamber of the drum 46 is always lled with water to a levelwhich is above the nipples 44 and 47. There is accordingly nopossibility for the escape `of sewergas rom'the drum 46 into the room,

cation `oifthe nipples 44 and 47 upon the sides of `the'drum 46, alsoprovide for the introduction of a cleanin rodA through the' drumintofthe parts which are connected with eitherofsaid nipples.

The closet drain preferably comprises the stem27' 4of. an integral-T-shaped fitting orinedyfvith an upturned receiving bend 52 socket forreceiving the lower end "of the 'closet vent connection 28.

Itis accordingly unnecessary ,for the length bf the closet drain 27 tocorrespond with lthe distance at which kthe closet islocated from thewall. It is merely necessary to so locate the stack 15 that the closetdrain 27 may be turned `to ben 52 of the drain 27 to register with thecloset outlet.

In theintermediate floors of the building, the vent connection 30, alsoextends to the branch vent pipe 56. In the lower floor of the building,the main vent pipe 17 may be directly connected with the fittin 41. Inthe top floor of the building allo the vent connections 28, 29 and AB0may extend to a horizontal portion of the main vent pipe 17.

While both threaded and calked joints are. shown upon the drawing, itwill be undeiwy stood that the several fittings may be con:

structed for the use of either of these forms of' joint, as desired,except that where the rotation 'of the fitting is inconvenient, a pipe.,as 29, which has a threaded connection at one end, will preferably beconnected to the corresponding fitting at the other end by means of acal ed joint.

When twoi `'ath rooms are to be located l upon the sanieiidor, the formof construction illustrated in Fig. 10, may be employed.

The construction here illustrated is the same as that already described,except that fittings 57 and 58, ezch vhaving two receiving inlets, as59, 60 or 1, 62, are employed in place of .j thefittin'gs 32 and 41,respectively. Furthermore the waste pipe branch 16 is formed with twoupwardly facing hubs or nipples63 and 64. When the hubs 63 and 64 areused,

the two closets may be alined upon'opposite sides of the wall, as 65, byinclining the two closet drains 27, as shown.
